Controlled, Repeatable Lubrication

The Duo^™ fluid controller delivers controlled, repeatable coil stock lubrication for narrow-width stamping applications. With Duo^™, you conserve lubricant by applying only what you need, directly to the stock, without overspray or excess fluid mess.

Duo^™ delivers stamping fluid to a Mini-Roller^™ or Uni-Roller^® S2 which then applies it neatly to one or both sides of the stock. The Duo^™ controller is designed for painless integration: Simply attach the provided rotation sensor cable, fill the lubricant reservoir, and mount and plug-in the Duo^™ controller to get started. Adjust the frequency and duration of lubricant dosing and let Duo^™ provide worry-free, consistent lubrication while you focus on making parts.

Consistent lubrication protects dies & improves efficiency
Reduces stamping fluid consumption significantly
Neat lubricant application keeps press areas clean

Combine Duo^™ with either Uni-Roller^® S2 or Mini-Roller^™ applicators.

The Internally-Fed Difference

Unist’s unique internally-fed roller design wicks and transfers a controlled amount of lubricant to the stock. Only what is needed is used - saving fluid and preventing messy, wet press areas.

Supplemental / In-Die Spray

The Duo^™ controller can also be used to control two Unist Airless Spray Nozzles for jobs where critical die components require additional lubrication.
